Light that looks bright may not answer the UVB question

What to know

Merck notes that lighting labels can be confusing and that transparent barriers can filter UVB. Requirements differ by species. Have a qualified professional review lamp type, position, barriers and the care plan instead of judging suitability by visible brightness.

Record the manufacturer, model and install date, and keep original instructions. The replacement schedule and placement must fit the product and species; this page does not give a universal distance or timer setting. After a change, document both the equipment and any observed behavior change. Do not use the worksheet to self-treat a suspected deficiency.

Make the next step clear

1. 1Identify the lamp.
2. 2Record barriers and placement.
3. 3Keep manufacturer instructions.
4. 4Review with the species care plan.
